The numeral 20 designates a blank, forming a bill holding unit 2i including a side 22 and side 23 foldable upon a transverse line 24. The side 22 is provided near its free end with the socket element 25 of a snap fastener. Formed integral with the side 23 is a partition unit including a side 26 foldable over the side 23 upon a longitudinal line 21. Formed integral with the side 26 is a side 28 foldable over the side 26 upon a transverse line 28. The side 28 has a longitudinal extension 30 foldable inwardly over the side 28 upon a longitudinal line 3!. The side 28 extends longitudinally outwardly beyond the longitudinal extension 30 to provide a folding flap 32, integral therewith, and this folding flap has tongues 33 and 34 which are foldable over the inner face flap 32 for forming a coin catching pocket 35. The tongues 33 and 34 overlap and are secured together by the stud element 36 of a snap fastener, to be secured within the socket element 25. The side 28 is formed separate from the side 22 a the blank is slit along the line 31 and the side 28 has a longitudinal tongue 38 extending outwardly beyond the folding line 39, which also constitutes the edge of the side 28. The slit 3! is oil-set lateralhr adjacent to the folding line 29 to form a stop element It).

The numeral 4| designates a separate lining blank which may be formed of cheaper material Figure 10 is a perspective view of a modified" '68 than is used for the blank 20. The blank 4| includes a section 42 and a section 46 foldable upon the outer side of the section 42, Figure 6, upon a longitudinal line 44. The section 42 has its inner edge arranged upon the inner face of the extension 66 and is secured thereto by a line of stitching 45.

The numeral 46 designates a lining blank disposed upon the inner face of a transverse extension 41 carried by the side 2.6 and secured thereto by a line ofstitching 46. The extension 41 is foldable upon the inner face of the side 26 upon a transverse line 49 and the stitching 46 is spaced. from the folding line 49, as shown.

The sections 42 and 46, Figure 6, have their inner faces coated with an adhesive or cement 56; the lining section 46 has its inner face coated with an adhesive or cement 6|; and the side 26 has a portion of its inner face adjacent to the longitudinal folding line 21 coated with an adhesive or cement, as shown at 62.

With the ton ues 66 and 64 folded inwardly. Figure 6, and secured together by the stud element 66 and the lining section 66 secured to the longitudinal extension 66, and the lining section secured to the transverse extension 41, the various portions of the folder may be assembled. The first step is to fold the longitudinal section 36 inwardly over the inner face of the side 26, Figure 7, upon line 6|, whereby the lining section 42 is arranged over the side 26 and the folding line 44 is disposedadjacent to and slightly inwardly of the central longitudinal line of the tongue 66. The lining section 42 is now pulled slightly so that its folding line 44 coincides with the central longitudinal line of the tongue 66 and the lining section 42 and tongue 66 are secured together by a longitudinal line of stitching 46', Figure 5. The lining section 46 i next folded back upon the longitudinal line 44 so that its face carrying the adhesive 66 is arranged uppermost, Figure 7, while the face of the lining section 42 carrying the adhesive 66 is arranged lowermost, Figure 7. This folding of the lining section 46 moves the line of stitching 45' inwardly slightly, since the tongue 66 folds upon the longitudinal line 39. The side 26 is now folded over the transverse line 29 and the lining section 46 will have its face coated with the adhesive brought down into engagement with the adhesive 62 applied to the side 26, Figure 8. The next step is the folding of the lining section 46 upon the transverse line 49 so that the lining section 46 passes between the side 26 and the coated face of the lining section 42. The adhesive 5| will secure the lining section 46 to the upper faces of the extension 66 and lining section 42, Figures 8 and 9, the upper face of the lining section 42 also having the adhesive 56. The lining section 46 having the adhesive 56 will be secured to the side 26 also having the adhesive 52. The assembled sides of the partition unit form a longitudinal pocket 56 for coin or the like and the side 26 and the lining sections 43 and 42 form a transverse pocket 44* open at the outer longitudinal edge of the partition. The lining sections 42 and 46 being foldable upon the line 44 form the bottom or closed edge of this transverse pocket. The line of stitching 45 being spaced from the folding line 6|, it is arranged well within the transverse pocket and hence is ordinarily covered from view. The line of stitching 45' i also disposed inwardly of the folded edge of the side 26, and is protected from view to some extent by that arrangement, and further, the folded over meeting edges of the sides 26 and 26 cover the edge of the partition adjacent to the line of stitching 46'. Further, the line of stitching 46 being spaced from the folding line 46, such line of stitching is arranged well within the lowtudinai pocket and is not readily visible. For these reasons, all lines of stitching are invisible when the parts of the bill folder are assembled and are in use in the closed position.

With the parts thus assembled, the sides 22 and 26 are included in the bill holding unit,.and the sides 26 and 26 are included in the partition unit having a folding edge 64 which is disposed near the transversefolding line 24,-the stop 46 extending to the folding line. The bills are arranged uporr the side 22 and 26 and the side 26 may be uppermost, and the partition unit is folded over the bills. The side 22 is folded upwardly over the partition unit and the flap 62 is brought down over the side 22 and is secured thereto by the elements 26 and 66. It is thus seen that the flap is carried by the partition and is connected with the side which does not carry the partition. This leaves th side 26 which carries the partition free at its outer corner. The folder may be arranged horizontally, Figure 2, and the outer comer of the side 26 bent back whereby the bills may be stripped from the folder without separating the flap from the side 22. When it is desired to remove the coins, the flap may be disconnected from the side 22 and the folder may be held in an inclined position with the flap 62 lowermost, Figure 3, and the coins will then slide from the pocket 66 upon the flap and be caught by the pocket formed by the tongues 66 and 64. The pocket 66 faces inwardly in an opposite direction'to the coin holding pocket.

In Figures 10 to 15 inclusive, I have shown a modified form of bill folder. This folder is formed from a single blank including a bill holding unit formed of sides 66 and 66. The side 66 is foldable upon the inner face of the sid 66 upon a transverse line 61. The numeral 66 designates a partition unit including a side 69 integral with the side 65 and foldable upon the inner face of the side 65 upon a longitudinal line 66. Formed integral with the side 69 is a side 6| foldable upon the inner face of the side 69 upon a transverse line 62. The line 62 is spaced from the line 61 and an inclined stop 66 is provided extending between these lines.

The side 69 is provided with a longitudinal ton ue 64 foldable over its inner face at its outer longitudinal edge and the side 6| has a longitudinal tongue 66 foldable over its inner face adjacent to its longitudinal edge remote from the tongue 64. When the side 6| is folded over the inner face of the side 69 the tongues 64 and 66 are disposed between these faces, to provide a suitable thickness, and these tongues and sides are stitched together by lines of stitching 66 and 61. The side 6| has a flap 66 integral therewith and foldable upon a transverse line 69 so that this flap is folded over the outer or bottom face, Figure 15, of the side 69 when the side 6| is folded over the face 69. The flap 66 has tongues 16 and 1|, foldable over the inner face of the flap 66, Figure 15, and portions of these tongues overlap and are secured together by a stud element 12 of a snap fastener. These tongues afford a pocket 16, for catching coins'or the like.

The assembled sides 69 and 6| afford a coin holding pocket 14, extending longitudinally of the folder and closed at its inner end. The partition provides a folding edge at the lin 62, about which the bills are folded. The open end of the coin receiving pocket is covered by the flap ide 58 and this side 58 carries a socket element 18, to receive the stud element 12. The flap is therefore secured to the side 58 which does not carry the partition. This leaves the side 55', which carries the partition, free at its outer corner so that this outer corner may be bent. back and the bills stripped from the folder without releasing the flap 68. When it is desired to'remove coins, the flap is moved to the open position and the folder inclined downwardly toward this flap whereby the coins will slide out of the coin receiving pocket and be deposited on the flap 88 and held thereon by the pocket I3. This pocket faces inwardly in an opposite direction to the open end of the pocket 14. In both forms of the invention, the folded over tongues of the flap produce rounded edges for the flap, which improves the appearance of the folder.

In Figures 16 to 20 inclusive, I have showna slight modification of the second form of the invention shown in Figures to 13 inclusive, whereby the partition is provided with key receiving pockets while the flexibility of the partition, at or near the free end of the coin receiving pocket, i retained. To accomplish this a layer or sheet 75 is arranged upon the bottom or outer face of the side 59 remote from the tongues 64 and 65. The end of the layer or sheet I5 adjacent to the line of folding 82 is cut away providing a curved edge i6, while the opposite end of the layer or sheet is cut away to provide an edge 11, affording a deep space. This space is tapered longitudinally and flares outwardly, the wide outer end of the space extending throughout substantially the entire width of the free edge of the side 59. This space terminates at a point 18. This leavesa relatively large area of the side 59 adjacent to its free edge uncovered so that the flexibility of the single layer of the side 59 is retained. The layer or sheet 15 is placed upon the side 59 before the side 59 is stitched to the side 58 and while the blank is in the position shown in Figure 16. The layer or sheet 75 is first stitched to the side 59 by a line of stitching 19, extending from points 88 to 8|, from points 8! to points 82, and from points 82 to a point 88. This line of stitching is of course sewed in a continuous manner. The side 59 is subsequently foldedover the side 58 and the lines of stitching 88 and 81 are employed to secure the side 59, tongues 88 and 85, and side 59 together, as described in connection with Figures 7 to 15 inclusive, and these lines of stitching 86 and 51 also pass through the longitudinal edges of the layer or sheet 55 to attach it to the adjacent side 59. The layer or sheet '55 and the lines of stitching forms" with the side 59 outer key receiving pockets 88, which taper inwardly, and these parts also form inner key receiving pockets 85 which taper inwardly. When the keys 85 are inserted in the key receiving pockets 88 the handle or head of the key does not project laterally beyond the outer ends of the pockets, and hence the space between the pockets remains uncovered substantially throughout its entire width, whereby the flexibility of the single layer of side 59 is retained. The keys 81 held within the pockets 85 have their heads arranged inwardly of the folding edge of the partition element.

The numeral 88 designates a flap carried by the side 58 and foldable upon, the line 89. This flap corresponds to the flap 88, Figures '7 to 18, inclusive. This flap has tongues 89 and ,98

formed integral therewith. The tongues 89 are foldableupon diagonal lines 9| and the tongue 98 is foldable upon a transverse line 92. The

tongues 89 and 88 are spaced, as shown, and

small tongues 98 are arranged between the same and are formed integral with theflap 88 and are foldable upon diagonal lines 98. tongues are first folded inwardly over the flap 88 and the tongues 89 are then folded over the flap and overlap with each other and the tongue 88 is then folded over the overlapping tongues 89 and the tongues 89 and 98 are secured together by the socket element 12". The socket 12' passes through the overlapping tongues 89 and 98, and is free from connection with the flap 88. The socket element 12' receives the stud element 12', secured to the side 58. The tongues 88 and 98 are alsofree from stitching with the flap 88. Due to the diagonal arrangement of the folded edges of the flap 88 and the tongues 89, when the flap 88 .is transversely arched, a resultant diagonal force is applied to the tongues 89, causing the tongues 89 and 98 to separate from the flap 88, which action increases toward the tongue 98. the side 58, and side 59, and terminate short of or are spaced from the transverse folding line 69 of the flap 88. Hence these tongues 89 are not folded transversely by the folding action of the flap upon the folding line 59, and a single layer structure is provided at the transverse folding line, producing a folded structure of the minimum thickness. The intermediate tongue 98 is attached to the tongues 89 at their outer ends, and when the flap 88 is transversely arched the resultant diagonal force applied to the tongues 89, swing the intermediate tongue 98 outwardly longitudinally of the flap 88 and separates the tongue 98 from the flap 88, and this action of the tongue 88 further aids in moving the tongues 89 from the upper surface of the flap 88. The diagonal folded edges of the tongues 89 converge outwardly toward the intermediate tongue 98 and cause the flap 88 to be tapered longitudinally in an outward direction. The arrangement provides a neat rounded effect at the free end of the flap. These assembled tongues provide a coin receiving pocket or cup for the coins discharging from the coin receiving pocket. If desired, the small tongues 93 may be omitted. The longitudinal tongues 89 terminate short of the folding line 89, Figure 17, as stated, and this provides an intermediate flap portion of single ply formation throughout its entire width and free from bellows at its longitudinal edges. This intermediate flap portion is of a suflicient length to be folded about the free end of the side 59, side 75, and side 55, when the folder is closed. This affords a thin construction.

All other parts of the folder will remain identical with those shown and described in connection with the second form of the invention, in Figures 10 to 15, inclusive. As shown in Figure 19. when it is desiredto remove coins or the like from the coin holding pocket, the side 59 may be moved to the open position, while the flap 88 projects forwardly beyond the outer end of the pocket. By applying inward pressure upon the longitudinal edges of the partition element, the side 59 is flexed laterally and outwardly with respect to the opposite side 58 of the coin holding These small The tongues 89 are separate from ciaimis:

time fiap extending over the open end of the pockets hold these keys spaced from this longitudinal flexing line. The key receiving pockets, with or without the keys, stiffen the side It, causing it to bend upon its central longitudinal line, between the edge 11.

The coin receiving pocket carriedby the flap .not only serves to stop the coins discharging from the coin holding pocket, but also serves to stiffen the free edges of the flap so that they will not tend to roll. This enables the flap to be formed of a thinner material than could otherwise be employed in the absence of the coin holding pocket on the ilap. i

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
